SPENCER, Ind.--(BUSINESS WIRE)--Cook Medical, one of the world’s largest private medical device companies, announced today a major step forward in the treatment of recto-vaginal fistulas, abnormal tracts that form between a women’s rectum and vagina. The Surgisis® Biodesign™ Recto-Vaginal Fistula Plug communicates with the patient’s body, signaling surrounding tissue to grow across the plug and allowing the fistula tract to close. This action supports the healing process by attracting cells and nutrients to the wounded area. Once the healing process is complete, the Surgisis Biodesign Recto-Vaginal Fistula Plug is undetectable and leaves a strong repair.
